Vizua vs TinyPNG: Which Image Compressor Is Better for Your Workflow?

TinyPNG has been the go-to image compressor for years. Vizua takes a different approach: same goal, but everything happens in your browser. Here's an honest look at how they compare.

What Each Tool Does

TinyPNG (also known as TinyJPG and Tinify) is a web-based image compression service that launched in 2014. You upload images to their servers, they compress the files using smart lossy compression, and you download the optimized versions. TinyPNG supports JPEG, PNG, WebP, AVIF, and animated PNG. They also offer a developer API, a WordPress plugin, and integrations with Photoshop and various build tools.

Vizua compresses JPEG, PNG, and WebP images entirely in your browser. No file ever leaves your device. You get an adjustable quality slider with a live preview showing the compressed result and file size before you download. Beyond compression, Vizua offers 71 image tools spanning conversion, editing, effects, and AI-powered features — but this comparison focuses on what both tools share: compression.

Compression Quality and Speed

TinyPNG is known for aggressive yet visually clean compression. Their approach selectively reduces the number of colors in PNG images and uses advanced encoding for JPEG files. Typical results show 50-80% file size reduction for PNG and around 40-60% for JPEG, depending on the source image.

Vizua uses optimized compression algorithms running locally in your browser. For JPEG, you control the quality level (typically 60-85 works well) and see exactly what the output looks like before saving. For PNG, the tool applies quantization that typically achieves 40-70% reduction. For WebP compression specifically, Vizua is one of the few tools offering a dedicated WebP compressor with adjustable quality.

Speed depends on different factors for each tool. TinyPNG's speed depends on your upload bandwidth, server queue, and download speed — fast connections see results in a few seconds. Vizua's speed depends entirely on your device's processing power. Modern phones and laptops compress a typical photo in under a second. For a deeper dive into how compression works, see our guide on compressing images without losing quality.

Supported Formats

TinyPNG covers more formats, including AVIF — a newer format that achieves even smaller files than WebP. That's a genuine advantage for workflows that need AVIF compression. Vizua's edge is the adjustable quality slider: you decide exactly how much compression to apply rather than accepting a fixed algorithm's judgment. For understanding the tradeoffs between these formats, see lossy vs. lossless compression explained.

Limits and Pricing

The API pricing for TinyPNG starts at $0.009 per compression after the free 500 monthly, dropping to $0.002 per image above 10,000. For developers building automated image pipelines, that's reasonable. For individuals who just need to compress a few photos, the free web tool works — if you stay within the 20-image, 5 MB limits.

Vizua has none of those limits. Compress one image or a hundred in a row. Work with files larger than 5 MB. No account, no API key, no monthly quota. The tradeoff is that Vizua doesn't offer an API for automated workflows — it's a browser-based tool for manual use.

Privacy: Where Your Files Go

TinyPNG uploads your images to servers hosted on Google Cloud Platform. Files are stored temporarily and deleted within 48 hours. They log request metadata (browser type, IP address, file fingerprint). It's a standard and well-documented approach, but your images do travel across the internet.

Vizua keeps everything on your device. Open the JPEG compressor, drop in a file, adjust quality, download. At no point does the image leave your machine. For anyone working with personal photos, client files, medical images, or anything under NDA, this distinction matters. We wrote more about why this is significant in our article about EXIF data and privacy risks.

Where TinyPNG Wins

Credit where it's due — TinyPNG has real strengths:

• Developer ecosystem. The Tinify API is well-documented, battle-tested, and integrates with WordPress, Photoshop, and CI/CD pipelines. If you need automated compression in a build process, TinyPNG is hard to beat.
• AVIF support. TinyPNG compresses and converts AVIF files. Vizua can convert to AVIF but not compress existing AVIF files.
• Animated PNG. TinyPNG handles APNG compression. Vizua doesn't currently support this format.
• Fully automatic. Upload, compress, download. No quality slider to think about. For users who want "just make it smaller" without decisions, TinyPNG's automatic approach is simpler.

Where Vizua Wins

• Complete privacy. Zero uploads. Zero server storage. Your files never leave your browser. Period.
• No limits. No 20-image cap, no 5 MB restriction, no monthly quota. Compress as many images as your device can handle.
• Quality control. The adjustable slider with live preview lets you find the perfect balance between file size and visual quality. Sometimes you want 90% quality for a hero image and 60% for thumbnails — Vizua lets you make that choice per image.
• Dedicated format tools. Separate tools for JPEG, PNG, and WebP, each optimized for that format's characteristics.
• Beyond compression. After compressing, you might want to resize, add a watermark, or convert to a different format — all without uploading to another service.
• No account needed. Open the page and start compressing. No signup, no email, no password.

The Bottom Line

TinyPNG is a solid compression tool with a strong developer API and years of refinement. If you need automated compression in a build pipeline or CMS, it's a great fit. If you're a developer working with AVIF, it's one of the few tools that compresses that format.

Vizua is the better choice when privacy matters, when you need to compress more than 20 images at a time, when your files exceed 5 MB, or when you want manual control over compression quality. The fact that everything runs locally means no usage limits and no data leaving your hands.

For most people compressing photos for a website, social media, or email — both tools get the job done. The question is whether you want to upload your images to a server or keep them on your device. That's a personal call, and now you have the facts to make it.
